CLAMP-BAND.

Specification of Letters Patent.

-- Patented Dec. 28,1915.

Application filed October 6,1914. Serial No. 865,236.

To all whom it may concern:

Be it known that I, FRANK C. STUCKEL,- a citizen of the United States, residing at acine, in the county of Racine, State of Wisconsin, have invented certain'new and useful Improvements in Clamp-Bands, of which .the following is hereby declared to be a full, clear, and exact description.

The invention relates to clamp-bands pipe onto its threaded junction member.

The improvement comprises a body length a sliding offset coupler to engage the head,- aid coupler being disposed at one side of the inner periphery of the clamp ring'but' shifting in curvilinear course at tangent con tact with the tube or like cylindric object. A separate set nut conveniently adjusts the coupler on screwing the nut along the threaded end into firm thrust against the coupler. I 5

On the drawings, Figure 1 is aplan view of the clamp-band in place about the pipe end to fasten the threaded union piece. Fig. 2 is an end view and Fig. 3 view in side elevation of the same parts. Fig. 4 is a separate view oftlie inverted coupler with head and tail ends of the clamp-band. cut across. Fig. 5 an elevation view in direction of the arrows, Fig. 4.

As shown by the drawings, the clampband comprises a body piece a generally of flexiblewire, enough fully to encircle the main tube 1), but ending at one terminal in an abruptly outturned head 0, while the op- 40 iposite end finishes in a straight stem or tail, alofng which slides a coupler d having nn abutment notch at its frontto encounter the outturned head a in ofi'set relation just across from the point of tange-Lt contact of the coupler cl with the tube 6, under stress of set nut a conveniently threaded to the stem to effect a push and pull strain on opposite termini of the encircling banda.

The coupler d is disposed at one side of tighter and tighter, without cross ridge or indent sinking deeper and deeper that would render the joint defective, as in some earlier forms where the band circuitisincomplete. used, for example, to fasten a section of hose Obviously, the tie-clip can be used to secure the staves of a barrel or tank instead. of. fastening a tubeseetion to its threaded union piece, as shown.

Details of structure can be varied by the mechanics skill without departure from the invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. An improved clamp-band, comprising a bodylength of flexible wire to encircle the main tube spirally, such body length having an abruptly outturned head at one end and a straight tail at the opposite end, with an adjustable coupler slidably mounted on said tail to engage said outturned head, said coupler being disposed at one side of the inner peri hery of the band and approximately in tangent contact with the clamped tube.

2. An im roved clamp-band, comprising a body length of flexible wire to encircle the main tube spirally, such body length having an abruptly outturned head at one end and a straight threaded tail atthe opposite end, with an adjustable coupler slidably mounted on said tail to engage said outturned head, said coupler being disposed at one side of the inner periphery of the band and approximately in tangent contact with the clamped tube, and an adjustable nut to shift said coupler in acourse tangential to the tube when the clamp-band is in oper- J.
